| Abstract | ||
| This paper aims to quantify the difference in amount of absorbed energy due to Impact on thin walled circular tubes that made from 2024-T135 aluminum alloy and that one made from composed material of the same dimensions. The two selected materials were subjected to the same Impact test conditions, which consist three different drop weights; each weight was dropped in three different impact speeds. The resulted deformations of the impacted specimens due to the drop weight and the impact speed were measured, then three terms were calculated depended on the measured deformation for each drop weight and impact speed, these are the mean impact load, specific energy absorption, and the absorbed energy. It was observed that the amount of absorbed energy is the same for the two selected materials under the same impact conditions, even when the measured deformation of the composite specimen is larger than that of the 2024-T135 specimen. | ||
